Note the Physics

• The increasing, decreasing, or constant spacing between successive tracks on the motion diagram is clearly reflected by the change in X or Y values on the position graph.
• Increasing, decreasing, or constant spacing with time on the motion diagram is an indication of increasing, decreasing, or constant speed (magnitude of velocity).
• The variation (or not) of the spacing with time on the motion diagram gives information about the acceleration:
  • Increasing spacing indicates acceleration in the same direction as the velocity.
  • Decreasing spacing indicates acceleration in the opposite direction to the velocity.
  • Constant spacing indicates zero acceleration.
